Explanation

Problem restatementCount distinct permutations of 'LEADER' considering repeated letters.

Given data

  • Letters: L, E, A, D, E, R (6 letters total).
  • Repetition: E occurs twice.

Concept/ApproachPermutations with repetition: total = 6! / 2!.

Step-by-step calculation Total arrangements = 6! / 2! = 720 / 2 = 360
